28 * The Frame class is the base sequence diagram graph nodes container.<br>
29 * For instance, only one frame can be drawn in the View.<br>
30 * Lifelines, Messages and Stop which are supposed to represent a Sequence diagram are drawn in a Frame.<br>
31 * Only the graph node added to their representing list will be drawn.
33 * The lifelines are appended along the X axsis when added in a frame.<br>
34 * The syncMessages are ordered along the Y axsis depending on the event occurrence they are attached to.<br>
